How Installing Energy-Efficient Windows in Lakewood Saves You Money

When you upgrade to energy-efficient windows, you may see several benefits, including:

  • Reduce your carbon footprint: You can reduce your carbon footprint by about 12% when you install Energy Star certified windows. In Lakewood, that’s about 460 pounds per year on average.
  • Protect your valuables: Many energy-efficient windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
  • Protect your investment: The older your home is, the more likely it is that getting new windows will benefit you. Older homes tend to have windows that are outdated, leaky or potentially even damaged in some way. Upgrading your windows could help raise the value of your home if you decide to sell.
  • Save on power bills: After you switch to energy-efficient windows, you can expect a reduction in your bills by about 12% because you’ll require less energy to heat or cool your house.

Estimated Cost of Window Replacement in Lakewood

Let’s take a look at the cost of updating your windows and the types of services offered by installers.

How Much Do New Windows Cost?

The typical cost to replace a single window is about $600 but can range anywhere from $200 to $1,200. How much it will cost is based on several factors, including size, number of windows, material, type, the location of your home and more.

It’s important to bear in mind that windows with the best efficiency may cost more initially but can save you hundreds of dollars via returns on your energy bills. Investing in Energy Star certified windows can save Lakewood homeowners $443+ a year when replacing single-pane windows.

Getting free quotes from multiple installers is the best way to figure out which one will work best for your budget.

What Services do Window Installers Offer?

In general, there are two kinds of window replacement services companies offer: full-frame and pocket installations.

A full-frame installation is a total window replacement. It involves removing the old window, the sill, and the exterior and interior trim. It also involves additional materials, such as insulation and drip edges, which increase the total cost of the project. It’s also worth noting that you may have to touch up the paint around the window after a full-frame installation. A pocket installation entails replacing a window within the existing frame, which is usually cheaper than a full-frame installation.

Your window installation company should be able to help you figure out which type of installation you need.

How We Choose the Best Window Installers in Lakewood

In our search to make your home improvements easier and more eco-friendly in Lakewood, the EcoWatch Reviews team landed on the above companies as the best window installation companies in the city. We’ve decided to evaluate the top window installers in Lakewood mostly based on energy efficiency, as the most sustainable option also benefits homeowners in many ways. Energy Star certified windows can cut your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology is based on the following factors:

Service Area

This one is self-explanatory, but we’ve chosen to highlight window installers that serve a wide variety of states and cities so you can find the best window installation company near you.

Work Quality

When choosing new windows, the quality and range of services can often play just as important of a role in overall efficiency and performance as the type of window you opt for. We do give window installers higher marks if they offer high-quality products, but we also consider workmanship as reflected in customer feedback.

Customer Reviews

We analyzed trends in recent customer feedback to find the companies with the most customer satisfaction, weighted by sample size. Customer satisfaction may be the most important factor, as it indicates the quality of services across most other categories, including warranty, quality of parts, professionalism, quality of installation, cost and more.

Cost

Cheaper windows don’t necessarily mean better windows, but we know many of our readers want to keep costs low when possible. When analyzing providers’ prices, we awarded higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.

Warranty

As discussed, windows are a substantial investment, so you’ll want to be certain that investment is protected. Window installation companies that provide lengthy warranties for products, parts and installation (aka workmanship) rank higher with EcoWatch.

Years of Experience

Due to Lakewood’s climate, homeowners need to be wary of low efficiency, water damage and rot. We factored in local experience to reflect the ability of Lakewood window companies to prepare homes for the climate. If a company has less than 10 years of experience, it loses points in this category.

Lakewood, CO Window Replacement FAQs

What is the average cost to install new windows in a home?

The average cost to install a window ranges between $450 and $650. There are several factors that affect the price, including how energy-efficient the windows are, styles and sizes of windows, local labor costs, the materials used in designing the windows, your property’s location and the number of windows.

Which type of window is the best?

Generally, double-pane windows will be more efficient than single-pane windows and windows that don’t open will be more efficient than windows that do. If you want to be sure you’ll have the most energy-efficient windows, look for models that have the blue Energy Star certification attached to them — they’re certified energy-efficient by the U.S. Department of Energy.

What services do window installation companies provide?

Window installers cover the entire process — from replacing old windows with brand-new ones to cleaning up after the installation. In addition, a lot of companies offer window manufacturing, customization and repairs.

Should I replace all my windows at once?

If your windows are greater than 20 years old, it’s most likely time to replace all of them. At that point, they are usually less efficient, leakier and/or more damaged than new windows. Doing your windows all at the same time will involve less paperwork and less stress.
